📌 Information & Algorithm

Given Input:

Enter a digit (0-9): 5

Expected Output:

Five

💻 Program Code

import java.util.Scanner;

public class DigitInWords {

    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);

        System.out.print("Enter a digit (0-9): ");
        int digit = sc.nextInt();

        switch (digit) {
            case 0: System.out.println("Zero"); break;
            case 1: System.out.println("One"); break;
            case 2: System.out.println("Two"); break;
            case 3: System.out.println("Three"); break;
            case 4: System.out.println("Four"); break;
            case 5: System.out.println("Five"); break;
            case 6: System.out.println("Six"); break;
            case 7: System.out.println("Seven"); break;
            case 8: System.out.println("Eight"); break;
            case 9: System.out.println("Nine"); break;
            default: System.out.println("Invalid input! Please enter a single digit (0-9).");
        }

        sc.close();
    }
}

🎯 How to learn from this example

First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.

🔥 Practice suggestion

Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
